B12 carb question


Recommended Posts

Posted

Have a leaking float, but only on side stand.

 

Stripped the carbs, floats all seem fine but copped the float valve seats are very loose in the body on 3 carbs. Can pull them out without any real resistance. I presume they should be a push fit with the orings? There's no way the orings are stopping fuel.

 

Anyone had this?

The brass well should push in firmly. If you need a few o-rings, p.m. me your address as have all the sizes in viton for c.v. carbs.

I buy those and other viton carb o rings in bulk, i pay about £5-£10 for a pack of 100 from reliable suppliers on eblag.

I use Simply Bearings. You have the added advantage of being able to order o-rings in different softness/hardness grades.  Far more options than Eblag in most cases.

Definitely worth a sticky post

1x3mm -mixture screw o-ring

1.5x3.5mm -carb top vacuum o-ring

1.5x5mm -float mechanism o-ring

1.5x7.5mm - float needle well o-ring

This is why I love this forum, I was talking with @davecara yesterday about new seals as all mine have dried out (this new fuel is awful)

Fowlers wanted £90 for the seals 

They're now in my basket on Eblag for a fraction of the price :D

Just be aware the a viton o-ring is roughly 3.5 times the price of a nitrile one. 

I'm not saying sellers on the bay are selling inferior o-rings, but can you tell the difference? That's why I only used a dedicated engineering based outlet so I sure what I'm getting.
